There is a very nice public demo by Kishori Sharan that shows how bounds work: http://www.java2s.com/Tutorials/Java/JavaFX_How_to/Node/Know_how_three_bounds_layoutBounds_boundsInLocal_and_boundsInParent_are_computed_for_a_node.htm.
It uses a deprecated API, so I've fixed it and added it to our GitHub as chapter2/other/BoundsDemo.java.
In the following screenshot from this demo, there is a Rectangle with rotation and translate transformations, and a shadow effect:
The smallest rectangle represents layoutBounds—it's the position of original Rectangle before any other changes.
The bigger rectangle around it is boundsInLocal ...
